A thread on what it means that FDA “cleared” the Apple Watch new EKG feature. First, here is FDA’s “clearance” letter if you want to read the full regulatory info: https://t.co/qu8CS54tUQ

There are some very important caveats to note. First, FDA did not “approve” the Apple Watch EKG. That would involve a lot of testing that Apple did not do. Don't be misled if you read news reporting about FDA "approval" or "approved." Sloppy and wrong for this product.
